Abstract

Analysis of a vehicle (4) is performed using multi-dimensional infrared image data acquired for the vehicle. A component of the vehicle can be identified within the infrared image data, and the infrared image data for the component can be analyzed to determine whether any condition (s) are present on the vehicle. One or more actions can be initiated in response to a determination that a particular condition is present. Additionally, visible image data can be used to supplement the infrared image data. Still further, infrared image data for similar components imaged concurrently with the component can be used to identify whether any condition (s) are present on the vehicle. Unlike prior art approaches in the rail industry, the analysis can be performed on rail vehicles within a classification yard.
